New research shows artificial intelligence can accelerate species discovery, improve ecosystem tracking and help meet global conservation targets  A new study from McGill researchers suggests the use of artificial intelligence (AI) to rapidly analyze vast amounts of biodiversity data could revolutionize conservation efforts by enabling scientists and policymakers to make better-informed decisions.

For people with a certain sleep disorder, a simple blood test could help predict the development of dementia years before symptoms appear, a new study indicates. Idiopathic REM sleep behaviour disorder (iRBD) causes people to physically act out their dreams while sleeping. The disorder is also associated with a very high risk of Parkinson's disease and a related condition called Dementia with Lewy Bodies.

A new way to measure male fertility has been discovered by researchers at the University of Waterloo, opening the door to the development of simple, inexpensive tests for clinical and at-home use. The research team combined expertise in sperm cell behaviour and interface science to determine that the movement of healthy sperm within semen reduces the force with which droplets stick to a water-repellent surface.

The prevalence of the four main types of this virus is less than 1% in young Quebecers aged 16 to 20 who have not received the vaccine. Less than 20 years after its introduction in Quebec, the human papillomavirus (HPV) vaccination program is so effective that even unvaccinated young people are benefiting from a form of immunity.

McGill team discovers a surprising electrical effect that remains stable despite dramatic changes in temperature Electronic devices rely on materials whose electrical properties change with temperature, making them less stable in extreme conditions. A discovery by McGill researchers that challenges conventional wisdom in physics suggests that bismuth, a metal, could serve as the foundation for highly stable electronic components.

Young female chimpanzees make their nests earlier and more often than young male chimps, demonstrating their independence right from the start, a new UdeM study finds. When do you make your bed? In the morning when you get up? Well, if you were a chimpanzee - our closest genetic relative, with about 99 per cent of our DNA - you'd more likely make it at dusk, just before you go to sleep for the night.

One-third of older Canadians at nutritional risk, study finds. One-third of Canadian adults aged 55 or older are nutritionally at risk, potentially leading to increased hospital stays, more emergency visits and physician consultations for possible infections, a new study found. The University of Waterloo researchers assessed data from more than 22,000 community-dwelling adults aged 55 and over from the Canadian Longitudinal Study on Aging.

Researchers at the UdeM-affiliated Saint-Justine Hospital and the ETS come up with a better way to compare magnetic resonance images taken at different institutions. From left to right: Dr Gregory A. Lodygensky, Jose Dolz, Farzad Beizaee and Christian Desrosiers Credit: CHU Sainte-Justine Magnetic resonance imaging (MRI) is an essential tool for medical clinicians, providing detailed views of the interior of the human body as well as valuable information on pathologies.

This protein plays an important role in maintaining the integrity of the barrier that controls exchanges between the blood and the brain When faced with chronic stress, some people develop anxiety and depressive symptoms, while others show great resilience. How can such differences be explained? It could be attributable, at least in part, to a protein that acts as a cannabinoid receptor and is present in the structure that controls exchanges between the bloodstream and the brain, suggests a study just published in Nature Neuroscience .

A new mathematical model developed at the University of Waterloo can determine a baby's overall drug exposure when their mother is taking medication. This is the first study to include drug transfer from the umbilical cord and through breastfeeding in determining the baby's total drug levels. The research team from the School of Pharmacy at Waterloo looked specifically at Levetiracetam.

Using the James Webb Space Telescope, astronomers led by UdeM graduate student Louis-Philippe Coulombe investigate the extreme weather patterns and atmospheric properties of LTT 9779 b. The exotic atmosphere of LTT 9779 b, a rare "ultra-hot Neptune," is coming to light thanks to observations via the James Webb Space Telescope led by Louis-Philippe Coulombe, a graduate student at Université de Montréal's Trottier Institute for Research on Exoplanets (IREx).

For the first time, a CRCHUM team has shown that, in mouse embryos, sister cells can communicate with each other through a bridge that allows them to die in a coordinated way.

Climate change limits progress on cleaning up the River Thames: study. A study led by a University of Waterloo researcher has learned that climate change is increasing the potential for algal blooms in the United Kingdom's River Thames despite a four-decade-long decline in phosphorus loads. The study completed a detailed analysis of the river's 150-year water quality record to learn this information.

Study finds practices in Buddhism and Christianity share a similar cognitive pathway to profound focus Two seemingly opposite spiritual practices - Buddhist jhana meditation and the Christian practice of speaking in tongues - have more in common than previously thought, a new study suggests. While one is quiet and deeply focused, and the other emotionally charged and expressive, both appear to harness the same cognitive feedback loop to create profound states of joy and surrender.

Proactively exposing ecosystems to mild environmental stressors appears to offer protection, study finds McGill researchers say their work could have important implications for managing biodiversity in the face of increasing anthropogenic stressors, such as climate change and pollution Mild, proactive exposure to environmental stress can help biological communities resist severe disturbances and maintain genetic diversity, a recent study from McGill University has found.

A groundbreaking study sheds new light on the role of the gut microbiome and metabolome in CTLA4 deficiency, a key factor in immune regulation and cancer mechanisms.

"Out of science fiction": First 3D observations of an exoplanet's atmosphere reveal a unique climate The first three-dimensional observations of the atmosphere of the exoplanet Tylos, in which astronomers from IREx participated, have revealed its unique climate. Joost Wardenier and Romain Allart, both IREx postdoctoral reseachers who contributed to the study.

The Calgary Stroke Program, a joint University of Calgary and Alberta Health Services initiative at Foothills Medical Centre, has been involved with three papers published this week in The Lancet and Lancet Neurology-the ESCAPE-NEXT trial, the FRONTIER trial, and an individual patient level meta-analysis across three trials.

For Feb.17, due to the storm, McGill teaching and work must be done remotely. Classes that cannot be done remotely will be cancelled. Labs and evaluations will be rescheduled, as appropriate. Only the McLennan Library is open for study ( see hours ). All other libraries are closed for the day. Pour le 17 février, en raison de la tempête, l'enseignement et le travail à McGill doivent être effectués à distance.

A new study sheds light on the obstacles faced by LGBTQ+ couples navigating medically assisted reproduction. For LGBTQ+ couples, getting pregnant can be an arduous process. There are countless forms to fill out and medical tests to take - many of which they feel are unnecessary - and a lot of invasive questions they have to field from friends and family who know precious little about the process.
